A pair of parallel intermediate plates 6 are arranged on the board 5 such that they can make a parallelogrammatic motion through a link 7 while being urges upward by means of a spring 8. A guide rod 9 is secured horizontally onto the intermediate plate and a top plate 10 is supported rotatably along the guide rod 9.
